E-M5 II Hi-Res vs E-M1 II Hi-Res image IQ.. What are the differences?

Hi everyone,

I love printing the images I've taken with my E-5, E-1 and E-P5 and so far, they look great when printed big. Lately, I'm intrigued by the Hi-Res feature of the E-M1 II and the samples I have seen are actually quite good and detailed despite showing some small artifacts which I don't think will show on the print sizes I plan to make -- 16x20 to 24x36". There are some scenes I have taken in the past with my E-5 and E-P5 that I would had wished it were taken with Hi-Res. I'm mainly interested in Hi-Res mode for urban scape and landscape and I'm well aware of the Hi-Res limitation.

So my question is -- how is the E-M1 II any better than the E-M5 II in regards to Hi-Res aside from the 80MP files it generates? Even the 64MP ISO 100 shots taken with the E-M5 II is cleaner than those taken with my E-P5.

Any thoughts and any samples you can share here if possible?

How about prints? What sizes have you printed up big thus far and do you see any artifacts..

The reason I'm interested in the E-M5 II is that, it's getting affordable buying it used or as a demo from a store.

HiRes mode uses electronic shutter. In the E-M5ii the maximum shutter speed is 1/20sec and in the E-M1ii is 1/50sec (slightly lower at high ISO).

As others have said the the HiRes mode of the E-M1ii handles minor movement much better than the E-M5ii.

In real world applications this effectively means better leaves and water surface in landscape photos.

In competely still images the higher resolution of the E-M1ii sensor will give you more detailed images but the amount of improvement is probably insignificant for most uses.

Neither cameras can produce useable HiRes images of subects with a lot of movement (people, pets etc.).

One way of tackling minor artefacts on HiRes files is to remove them using the .ORI file created when the HiRes shot was taken. The .ORI file is simply a renamed .ORF file of the first of the 8 shots used to create the HiRes shot. Most photoprocessing software doesn't recognise the .ORI file extension so rename it to .ORF but don't forget to change the rest of the file name or you may overwrite the HiRes .ORF file of the same name. It is then a simple matter of masking the arefacts and blending the 2 .ORF files in the software of your choice. This gives you a MixedRes shot with static parts HiRes and moving parts standard res.

Since the fastest shutter speed of the .ORI file is slow ( 1/20 on E-M5ii and 1/50 on E-M1ii) you may still get movement bluring but not the irritating artefacts.

I would suggest you take a few of your typical landscape shots at 1/20 sec on your current camera. Carefully look at the sharpness of leaves, water etc. as this may be the maximum sharpness you may get of moving objects using HiRes mode. If you are satisfied with it then the E-M5ii HiRes mode won't disappoint you. Try again at 1/50 sec to see what the E-M1ii will give you. In both cases the static part of of your images will be much sharper in HiRes mode but it will be the areas with movement that will determine whether the image is usable or not.

The E-M10iii will soon be announced. I think it is highly likely it will have a HiRes mode. Whether it will be as good as or better than the existing HiRes modes is uncertain.

your information is totally wrong . hi res only uses the lower shutter speed for FLASH photography.
